The In-pot Car Retarder automatic open device
Technical field
The utility model relates to a kind of device of the unlatching of coal mine shaft cage interior car arrester, belongs to the coal mine machinery equipment technical field.
Background technology
Existing cage stop device opening and closing device is by crossbeam, spider, fixed guide, guide rail, bearing, pull bar, connecting rod, formations such as Electrohydraulic push rod, wheel, permanent magnet proximity switch, roller.Fixed guide is connected and fixed by spider and crossbeam.Wheel is installed on the guide rail with bearing pin, guide rail is inlaid on the crossbeam by four wheels, connecting rod one end and guide rail are connected and fixed, the other end and pull bar are hinged, and an end and the bearing of pull bar are hinged, and the piston rod of the other end and Electrohydraulic push rod is hinged, bearing is fixed on the crossbeam, Electrohydraulic push rod is hinged on the crossbeam by a support, and permanent magnet proximity switch is installed in an end of crossbeam, and roller is connected with cage stop device link gear.Whole opening and closing device is installed on vertical shaft well head or the shaft bottom upper jacket frame beam, in the middle of two cages.
Its principle of work is: when cage rises or descends when putting in place, roller enters and is connected guide rail with cage chair and along fixed guide and guide rail movement, at this moment Electrohydraulic push rod energising work, piston rod stretches out pushing drawing rod and rotates, and drivening rod, guide rail move along crossbeam straight line (left), and roller and cage interior car arrester link gear are moved together, and guide rail moves to permanent magnet proximity switch and disconnects, Electrohydraulic push rod quits work, and guide rail stops to move.At this moment the cage interior car arrester is opened, and mine car can be pushed out in jar.On the contrary, the Electrohydraulic push rod work of switching on again, the piston rod withdrawal, guide rail moves right, and when piston rod was reduced to the end, In-pot Car Retarder was closed, and the outer mine car of cage just can push cage.Existing cage stop device opening and closing device, complex structure, volume is big, the investment cost height, difficulty is regulated in installation and maintenance, and forced stroke is regulated loaded down with trivial details, and In-pot Car Retarder opens and closes and can not accurately put in place, and is fragile, influence service life, guide rail is by the exterior power source Control work, and power consumption is big.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, and installation, maintenance is convenient, the In-pot Car Retarder automatic open device of energy savings.
The purpose of this utility model is to realize like this, the In-pot Car Retarder automatic open device, it is characterized in that being provided with guard rail, bar press structure and spring installation, guard rail is fastened on the cage chair, one end and the guard rail of bar press structure are articulated and connected, and spring installation is installed in the following of the bar press structure other end and is supporting the bar press structure.
Described bar press structure is provided with angle steel I, angle steel II, pressing plate and brace panel, and the two ends of angle steel II are welded to connect with the end of two angle steel I respectively, and brace panel is welded on the other end of angle steel I, and pressing plate is welded on the angle steel II.Described spring installation is provided with spring, suspension, hex bolt, suspension is weldingly fixed on the rocking arm channel beam below the bar press structure, hex bolt is installed on suspension and the bar press structure, and spring is set on the hex bolt between bar press structure and the suspension.
Its principle of work is: when mine car is pushed to the rocking arm of cage chair by car puller, the mine car wheel is pressed on the bar press structure simultaneously, mine car continues to advance forward, bump jar interior mine car, at this simultaneously, because the weight of mine car makes the bar press structure rotate around jointed shaft, spring by compression, pressing plate is pressing the depression bar on the In-pot Car Retarder leverage to move downward together, and In-pot Car Retarder is opened, and mine car is by knocking-on cage in jar, the mine car that has just entered cage breaks away from the moment of pressing thick stick, because the effect of spring force is lifted the pressure thick stick and set back, the In-pot Car Retarder leverage is held up traffic along with moving on the depression bar to set back.
The utility model is simple and reasonable, manufactures easily, and cost is low, and volume is little, and is in light weight, convenient for installation and maintenance.Compare with existing cage stop device opening and closing device, owing to do not need Power Drive Unit, so energy saving, be swift in motion, safe and reliable.Can be widely used in mine mechanical engineerings such as colliery, the excellent popularization using value is arranged.
